7.4.5
MAC Filter
This screen allows you to configure the Device to give exclusive access to specific
devices (
Allow
) or exclude specific devices from accessing the Device (
Deny
).
Every Ethernet device has a unique MAC (Media Access Control) address. The MAC
address is assigned at the factory and consists of six pairs of hexadecimal
characters, for example, 00:A0:C5:00:00:02. You need to know the MAC
addresses of the devices to configure this screen.
WPA2
Preauthentication
This field is available only when you select
WPA2
.
Pre-authentication enables fast roaming by allowing the wireless
client (already connecting to an AP) to perform IEEE 802.1x
authentication with another AP before connecting to it. Select
Enabled
to turn on preauthentication in WAP2. Otherwise, select
Disabled
.
Network Re-auth
Interval
This field is available only when you select
WPA2
.
Specify how often wireless clients have to resend usernames and
passwords in order to stay connected. Enter a time interval between
10 and 2147483647 seconds.
Note: If wireless client authentication is done using a RADIUS
server, the reauthentication timer on the RADIUS server
has priority.
Group Key
Update Timer
The
Group Key Update Timer
is the rate at which the AP (if using
WPA(2)-PSK
key management) or
RADIUS
server (if using WPA(2)
key management) sends a new group key out to all clients. The re-
keying process is the WPA(2) equivalent of automatically changing
the WEP key for an AP and all stations in a WLAN on a periodic basis.
Setting of the
Group Key Update Timer
is also supported in
WPA(2)-PSK
mode. The Device default is
1800
seconds (30
minutes).
Authentication Server
IP Address
Enter the IP address of the external authentication server in dotted
decimal notation.
Port Number
Enter the port number of the external authentication server. The
default port number is
1812
.
You need not change this value unless your network administrator
instructs you to do so with additional information.
Shared Secret
Enter a password (up to 31 alphanumeric characters) as the key to be
shared between the external authentication server and the Device.
The key must be the same on the external authentication server and
your Device. The key is not sent over the network.

SSID
An SSID profile is the set of parameters relating to one of the Device’s
BSSs. The SSID (Service Set IDentifier) identifies the Service Set with
which a wireless device is associated.
This field displays the name of the wireless profile on the network. When
a wireless client scans for an AP to associate with, this is the name that
is broadcast and seen in the wireless client utility.
Security
This field indicates the security mode of the SSID profile.
